On the application of the ward by next friend or the sureties on the conservator's bond, showing satisfactory cause, the court may issue process to the conservator, requiring him or her to appear and show cause why he or she should not make a partial settlement of his or her conservatorship, of which process there must be service 10 days before the day appointed for the appearance of the conservator. If, on the hearing, it should appear that there is no satisfactory cause for ordering such settlement, the application must be dismissed at the costs of the next friend or the sureties on the conservator's bond, as the case may be.
